Liverpool are in the middle of a huge week, and so it isn't exactly the ideal time for an injury crisis.

But they're in one.

With the Merseyside derby at Goodison Park on the horizon as well as the second leg of the Champions League quarter-final against Manchester City to play, Jurgen Klopp is likely to be without a host of his stars.

So the German has turned to stars from the club's Academy to train with the first-team at Melwood this week, with some likely to be involved in the matchday squads in the next week.

But who are those players? Our friends at the Liverpool Echo have been taking a look.

Widely regarded as one of the hottest properties at Kirkby, it has been a stunning rise up the ranks for the Scouse midfielder.

Having turned 17 in January, Jones has found himself promoted into the Under-23s after spending half a season under the tutelage of Steven Gerrard.

Born in Liverpool city centre, the teenager is both dynamic and energetic, capable of running a game from deep or influencing the game higher up the field.

He is both a goalscorer and creator, notching 14 goals for the Under-18s in just 27 appearances, and also bagging five in the UEFA Youth League.

It is little wonder there is such excitement surrounding him, even if Gerrard is keen to quell the expectations on the youngster.

Signed from Manchester City in 2016, the Portuguese wide man is quick, direct and improving his power all the time as his development under Gerrard continues.

The 17-year-old has scored seven goals this season for the Under-18s, including a phenomenal hat trick against Blackburn in January.

He was also an ever-present in the UEFA Youth League and scoring a brilliant solo effort against Manchester United in the last 16.

The Portugal youth international offers something few others do, with that speed and trickery out wide in the mould of Sadio Mane and Mohamed Salah.

Eyebrows were raised when the centre-back was named in the squad for Wednesday's 3-0 win over Manchester City - but with so few defenders available to Klopp, the Irish youth international was an obvious call-up.

He's been with the Reds since 2012, joining as a 13-year-old, and has developed into a good, strong ball-playing centre half at that level.

Already named as an unused substitute in the FA Cup against Exeter in January 2016, Masterson has found himself as a crucial part of Neil Critchley's Under-23s for the latter part of the campaign.

A Liverpool shirt with H. Kane on the back would be enough to make supporters dream.

But the Bristol-born teenager is hoping he can craft his own path despite his much more famous namesake.

A midfield player with the ability to play both deeper and in more advanced positions, Kane has spent the entire season with the Under-23s, and has recently taken the armband in defeats against Tottenham and West Ham.

He is perhaps best in front of the defence, serving as a shield.

Perhaps the most unknown of the five, Phillips arrived in 2017 after rising through the ranks of Bolton's Academy.

Just two days before the call from Liverpool came, the defender had decided to take a four-year degree course at the University of North Carolina at Charlotte on a football scholarship - with a plan to get drafted to the MLS.

Now 21, Phillips settled in well with the Under-23s at centre-back last season, and began this campaign in similar fashion.

But injury saw him miss almost six months of action, and only just returned last month, facing Manchester United at Anfield.

The powerful centre-half is in need of minutes and his time at Melwood will serve him well.
